The fastest way is from inside the app:
1. Open Mines of Idle Doomath.
2. Open the menu and go to the Account tab.
3. If you are not signed in, sign in first (email, or the provider you registered with).
4. Tap “Delete account” and confirm.
Your account is deleted immediately and you are signed out on all of your devices. No email is needed.
If you no longer have the app installed, email minus4kelvin@gmail.com from the email address you signed up with, with “Account deletion” as the subject. To protect your data, we only act on a request that comes from the registered address. The account will be deleted within 30 days of the request.
Deleting your account permanently erases, from our server: the account and its sign-in credentials (email and password, and any linked Google or Apple identity); every cloud save linked to the account, on every device; your leaderboard entry; and the purchase records linked to the account, so they cannot be restored onto a new account. Every signed-in device is signed out.
Data that exists only on your device (the local game save, settings, and local stats) is not affected by an account deletion — erase that separately in the app (Save → “Erase all data”).
Deleted data is removed from the live database immediately. Our only other copies are routine nightly server backups, which are rotated and overwritten; we do not retain deleted data beyond 30 days and never use it for any purpose after deletion.
If you signed in with Google or Apple, the data those companies hold is managed by their own settings and policies. If you bought something through Google Play or the App Store, the store keeps its own transaction records for legal reasons that we cannot delete; we delete only our own copies.
